Mixing paddle



Patented Mar. 19, 1946 UNITED STATES PATENT OFFICE MIXING PADDLE Frederick H. Valiton, Deer Lodge, Mont. Application January 12, 1945, Serial No. 572,549

3 Claims.

This invention relates to mixing paddles and more particularly, to a mixing paddle for stirring lumpy and hard to dissolve mixtures.

Another object of the invention is to provide a mixing paddle which will mix as well as strain the mixture.

A further object of the invention is to provide a mixing paddle that will scrape all lumps or sediment from the container and thoroughly mix and separate the lumps and sediment.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate corresponding parts throughou Figure 1 is a side View of the device embodying the invention, in operating position.

t Figure 2 is a front view thereof in normal posiion.

Figure 3 is a rear view of the same.

Figure 4 is a perspective view of the perforated plate l5 and Figure 5 is a view of fore being completely formed.

Referring more particularly to the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, l designates the mixing paddle having a handle H to which is attached by means of a rivet, a perforated plate l2 and a fiat spring loop I4 which gives the paddle ill more flexibility and prevents breakage, secured to the lower end of spring [4 by means of rivets is a perforated plate IS. The flat surface of plate I is of a sufficient width to register with the flat surface of plate l2, projections l6 and I1 formed at the upper end of plate [5 are bent in U-loops l8 and I9 and are adapted to engage the plate l2 at the upper end thereof. The loops l8 and I9 determine and regulate the distance, the plates I 2 and I5 can beseparated to prevent breakage of the spring loop M. The flat surface of the plate l5 will however remain parallel to and in face to face relationship with the flat surface of the plate I 2 since the flat spring loop I4 normally holds the inner surfaces of the perforated plates I2 and I5 together. But during operation of the paddle when the shoe 23 is drawn across the bottom of the container the perforated plates l2 and I5 will be separated, against the tension of the spring loop l4, the point of separation being determined by the U- loops l8 and I9. With the two plates normally held together in this manner the device can be used as an ordinary paddle.

The sides or edges of plate l5 are bent to form wing portions 20 and 2|. The lower end portion 22 of plate I5 is bent at an angle and is adapted to have riveted thereto a shoe 23 which is made the perforated plate I 5 bespring connected to said handle, a

of fiber Or an other like material. This shoe creates a drag on the plate I5 when the mixing paddle in is drawn across the container. Thus all lumps or sediment are scraped from the bottom of the container and forced up between the plates I2 and I5. Therefore when the paddle I0 is drawn across the container, the shoe 23 acting as a drag forces the plates [2 and I5 to be separated to an angle determined by the U-loops l8 and I9, as shown in Fig. 1. The lumps and sediment scooped upward by the shoe 23 are directed by means of wing portions 20 and 2| toward the flat surfaces of plates I2 and I5.

When the mixing paddle in is moved in the opposite direction, the plates [2 and I5 are forced together and the lumps and sediment are compressed by the plates l2 and I 5 and forced through the perforation 24 in both plates. This operation is thus performed with the aid of the tension of the spring loop [4 which acts in the dual capacity of spring and hinge, since the spring loop l4 normally holds the inner fiat surfaces of the plates l2 and I5 together and pre-- vents displacement of the plates during the mixing operation.

By this operation, the mixture is thoroughly mixed and strained in one operation.

While the plates l2 and I5 as shown are perforated, it is not deemed to be beyond the scope of the invention to make these plates of a mesh material that can be retained in place by means of a frame conformingto the shape and size of plates l2 and I5.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape, and arrangement of parts, may be resorted to without departure from the spirit of the invention or the scope of the subjoined claims,

Having thus described the invention, what is claimed is:

1. A mixing paddle, comprising a handle, a perforated plate attached to said handle, a loop perforated plate attached to said spring, said spring being adapted to position said plates in angular relationship to each other and means on one of said plates for limiting the angular relationship of said plates.

2. The invention as described in claim 1 wherein one of said plates is provided with wing portions.

3. The invention as described in claim 1 wherein one of said plates is provided on the sides thereof with inwardly inclined wing portions and on the bottom edge thereof with an inwardly inclined scraper portion.
